Background: A popliteal vein aneurysm (PVA) is a rare vascular abnormality that can lead to the formation of venous thrombi, resulting in potentially life-threatening pulmonary embolism (PE). Methods: We present the case of a 30-year-old female who presented with recurrent pulmonary embolism complicated by cardiorespiratory arrest. Emergency thrombolysis was initiated, which successfully stabilized the patient. Further diagnostic evaluation, including imaging studies, revealed the presence of a giant popliteal vein aneurysm (60/70 mm) as the underlying cause of recurrent embolism. Results: The patient underwent surgical repair of the popliteal vein aneurysm to prevent further thromboembolic events. The procedure was performed successfully, and the patient recovered favorably. Conclusions: This case underscores the importance of recognizing PVA as a potential cause of recurrent PE, particularly in young patients without typical risk factors. Full article

Sudden unexpected death in epilepsy (SUDEP) is sudden, unexpected, witnessed or unwitnessed, nontraumatic, non-drowning death that occurs in a person with epilepsy. SUDEP is the leading cause of epilepsy-related death in adults with epilepsy, with an incidence of about 1.2 per 1000 person-years in the general epilepsy population. Recent studies have shown similar prevalence in the pediatric population too. Although the precise mechanism remains unclear, well-documented cases of SUDEP suggest that a generalized tonic clonic seizure-induced, centrally mediated change in cardiorespiratory function leads to terminal apnea and cardiac arrest. Risk factors include generalized tonic clonic seizure frequency, duration of epilepsy, nocturnal seizure, and certain genetic syndromes. Orexin, adenosine, and serotonin neurotransmission have been explored as novel drug targets to mitigate SUDEP risk. Neurostimulation and resective epilepsy surgery have been reported to have beneficial effects on long-term SUDEP risk as well. Future studies may aim to clarify the role of sleep and other comorbidities in SUDEP pathophysiology. Full article

Cystic fibrosis (CF) is a multisystemic disease caused by a genetic defect, namely a mutation in the CFTR gene, that results in the production of an abnormal protein that regulates the flow of chloride ions through epithelial cells, leading to the dehydration of secreted mucus and changes in its biological properties. Chronic inflammation and recurrent respiratory infections progressively damage lung tissue, leading to respiratory and cardiorespiratory failure. This study aims to present a clinical case and explore the clinical changes in CF that may influence the provision of pre-hospital first aid. The study presents a case report of a 23-year-old CF patient undergoing evaluation for lung transplantation, infected with Pseudomonas aeruginosa and Staphylococcus aureus with the MSSA phenotype, and in a severe condition due to infectious exacerbation. Despite antibiotic treatment, the patient’s condition deteriorated, leading to respiratory failure and cardiac arrest. Emergency measures were taken to maintain airway patency—the patient was sedated, intubated, and connected to a ventilator. CF involves systemic complications that, during exacerbations, may require urgent interventions. Cystic fibrosis is associated with multiple systemic complications, some of which may, during exacerbations, require emergency medical interventions. Providing care to this patient group involves specific procedures addressing the consequences of the underlying disease. Due to increasing survival rates and the emergence of new phenotypes, there is a need for the continuous education of medical personnel, including emergency responders, regarding the management of genetically determined diseases. This study underscores the importance of recognizing CF’s complex nature and adapting emergency care accordingly to ensure timely and effective intervention in life-threatening situations.

Background/Objectives: The incidence, timing, and predictors of hemodynamic and respiratory deterioration in patients with high-risk or intermediate-high-risk pulmonary embolism (PE) undergoing pulmonary mechanical thrombectomy (PMT) remain poorly understood. This hemodynamic and respiratory instability can lead to modifications in the anesthetic management. This study investigates these key factors and quantifies the 30-day mortality following thrombectomy. Methods: A retrospective study was conducted on 98 patients aged ≥18 years who underwent PMT. Patients were categorized based on the occurrence of cardiac arrest (CA). Results: Of the 98 patients, 34 had high-risk PE, 62 intermediate/high-risk, and 2 low risk. There were 27 cases of CA, 17 pre- and 10 intra-PMT. An SBP < 90 mmHg increases the risk of CA by 33 (p < 0.001); men have an 8-fold higher risk than women (p = 0.004); SpO₂ <90% by 6 (p = 0.012); and pre-existing respiratory conditions increase the risk by 4 (p = 0.047)). N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were 8206 ± 11660.86 and 2388.50 ± 5683.71 pg/mL (p = 0.035) in patients with and without CA, respectively. During PMT, 14% of patients required increased vasoactive drug use, and 38.77% were intubated, including 12 who required ECMO support. Sedation was administered in 64.3% of patients, while general anesthesia was used in 38.8%, with a preemptive indication in 23.5%. The survival rate of patients without CA before and/or during PMT was 96%. Conclusions: While PMT was successfully performed in all patients, hemodynamic and respiratory instability remained a significant concern. More than 10% of patients experienced severe hemodynamic instability, primarily during thrombus extraction, requiring conversion from sedation to general anesthesia. Male sex, pre-existing respiratory disease, SpO₂ < 90%, and SBP < 90 mmHg were associated with an increased risk of CA. Additionally, elevated NT-proBNP levels were linked to a higher incidence of CA. Full article

Background and Clinical Significance: The current paper presents a retrospective case of a 79-year-old female patient admitted to the Dermatology Clinic of Emergency City Hospital in Timisoara, Romania, in January 2022, reporting intense pruritus and burning sensation of the skin exacerbated at night. Case Presentation: The previously mentioned symptoms appeared approximately six months prior, with gradual and continuous progression. Clinical examination revealed widespread hyperkeratosis on diffuse erythematous background across the entire body, accompanied by crusted lesions predominantly on the arms and legs. Laboratory values showed elevated absolute eosinophil count as well as a positive culture swab to Staphylococcus aureus. Two incisional skin biopsies were performed. Microscopic examination in Hematoxylin–Eosin staining revealed thickened stratum corneum with numerous oval-shaped mites with exoskeleton and striations and moderate perivascular lympho-eosinophilic infiltrate in the superficial dermis, leading to a positive diagnosis of crusted scabies. Following etiological treatment, the patient’s evolution was undulating and on the 10th day of hospitalization presented marked dyspnea, followed by cardiorespiratory arrest, leading to the patient’s death. Conclusions: The patient’s outcome could be explained by a Th2-mediated allergic response to Sarcoptes scabiei allergens, in addition to the presence of Staphylococcus aureus on the damaged skin, as dysbiosis can further support an uncontrolled Th2 reaction, leading to anaphylaxis.

Background/Objectives: This study sought to evaluate the clinical profile, in-hospital management, prognosis, and survival of patients treated for cardiac arrest using extracorporeal therapy in a third-level Spanish hospital before and after the therapy was protocolised. Methods: This study is a historical single-centre cohort study that was conducted from January 2009 to February 2024. In 2019, an in-hospital extracorporeal reanimation therapy protocol was established in the centre’s Coronary Intensive Care Unit. As a result, the cohort was split into two groups: the Pre-Protocol group (between 2009 and December 2018) and the Post-Protocol group (between 2019 and February 2024). Results: A total of 26 patients were recruited, i.e., 10 in the first cohort and 16 in the second, with acute myocardial infarction being the most prevalent cause in both cohorts. A 30% (3) to 43.65% (7) increase in survival was observed between the two cohorts (p = 0.48), with CPC 1–2 neurological functionality exceeding 85% of cases in both cohorts (p = 0.7). The mean time from cardiac arrest to the application of extracorporeal therapy decreased from 104.1 min to 41.87 min (p = 0.09). The longer duration of ECMO (p = 0.03) and the longer hospital stay (p = 0.002) are due to a higher survival. Conclusions: The results show a trend in improvement outcomes. The small cohort size makes it difficult to draw robust conclusions, but we want to highlight the importance of applying a specific protocol based on standardised patient selection criteria and the establishment of extracorporeal reanimation therapy.

Developing interfaces for seizure diagnosis, often challenging to detect visually, is rising. However, their effectiveness is constrained by the need for diverse and extensive databases. This study aimed to create a seizure detection methodology incorporating detailed information from each EEG channel and accounts for frequency band variations linked to the primary brain pathology leading to ICU admission, enhancing our ability to identify epilepsy onset. This study involved 460 video-electroencephalography recordings from 71 patients under monitoring. We applied signal preprocessing and conducted a numerical quantitative analysis in the frequency domain. Various machine learning algorithms were assessed for their efficacy. The k-nearest neighbours (KNN) model was the most effective in our overall sample, achieving an average F1 score of 0.76. For specific subgroups, different models showed superior performance: Decision Tree for ‘Epilepsy’ (average F1 score of 0.80) and ‘Craniencephalic Trauma’ (average F1 score of 0.84), Random Forest for ‘Cardiorespiratory Arrest’ (average F1 score of 0.89) and ‘Brain Haemorrhage’ (average F1 score of 0.84). In the categorisation of seizure types, Linear Discriminant Analysis was most effective for focal seizures (average F1 score of 0.87), KNN for generalised (average F1 score of 0.84) and convulsive seizures (average F1 score of 0.88), and logistic regression for non-convulsive seizures (average F1 score of 0.83). Our study demonstrates the potential of using classifier models based on quantified EEG data for diagnosing seizures in ICU patients. The performance of these models varies significantly depending on the underlying cause of the seizure, highlighting the importance of tailored approaches. The automation of these diagnostic tools could facilitate early seizure detection. Full article

Noncardiogenic pulmonary edema after cardiac surgery is a rare but severe complication. The etiology remains poorly understood; however, the issue may arise from multiple sources. Possible causes include a significant inflammatory response or an autoimmune process. Pulmonary edema resulting from noncardiac etiologies can necessitate extracorporeal membrane oxygenation (ECMO) because most of the cases present a substantial volume of fluid expelled from the lungs and the medical team must manage the inability to achieve effective ventilation. A 64-year-old patient with known heart disease was admitted to our clinic with acute pulmonary edema. His medical history included Barlow’s disease, severe mitral regurgitation (IIP2), moderate–severe tricuspid regurgitation, and moderate pulmonary hypertension. The patient had a coronary angiography performed in a prior hospitalization before the surgical intervention which indicated the absence of coronary lesions. Preoperative screening (nasal, pharyngeal exudate, inguinal pouch culture, and urine culture) was negative, with no active dental infections. The patient was stabilized, and 14 days post-admission, mitral and tricuspid valve repair was performed via a thoracoscopic approach. After being admitted to intensive care post-surgery, the patient quickly developed pulmonary edema, producing a large volume (4.5 L) of yellow secretions through the intubation tube followed by hemodynamic instability necessitating high doses of medications to support circulation but no cardiorespiratory arrest. Due to his worsening condition, the patient was urgently taken back to the operating room, where veno-venous extracorporeal membrane oxygenation (VV-ECMO) was initiated to support oxygenation and stabilize the patient.

Background: Extracorporeal cardiopulmonary resuscitation (eCPR) offers cardiorespiratory support to patients experiencing cardiac arrest. However, this technology is not yet considered a standard treatment, and the evidence on eCPR criteria and its association with survival and good neurological outcomes remains scarce. Therefore, we aimed to investigate the overall mortality and risk factors for mortality. Moreover, we provide a comparison of demographic, clinical, and laboratory characteristics of patients, including neurological outcomes and adverse events during support. Methods: This retrospective analysis included in-hospital and out-of-hospital cardiac arrest patients who received eCPR and were admitted between January 2008 and June 2022 at a tertiary and trauma one-level university hospital in Austria. Results: In total, 90 patients fulfilled inclusion criteria, 41 (46%) patients survived until intensive care unit discharge, and 39 (43%) survived until hospital discharge. The most common cause of cardiac arrest was myocardial infarction (42, 47%), and non-shockable initial rhythm was reported in 50 patients (56%). Of 33 survivors with documented outcomes, 30 had a good recovery as measured with Cerebral Performance Category score, 2 suffered severe disability, and 1 remained in a persistent vegetative state. Finally, multivariate analysis identified asystole as initial rhythm (HR 2.88, p = 0.049), prolonged CPR (HR 1.02, p = 0.043), and CPR on the weekend (HR 2.57, p = 0.032) as factors with a higher risk of mortality. Conclusions: eCPR-related decision-making could be additionally supported by the comprehension of the reported risk factors for mortality and severe disability. Further studies are needed to elucidate the impact of peri-arrest variables on outcomes, aiming to improve patient selection. Full article

Background: Cardiac injury caused by a sharp object is a medical and surgical therapeutic challenge. Mortality risk factors have been identified but there are major discrepancies in the literature. The aim of this study was to analyse the management of victims of penetrating cardiac injuries before and after admission to hospital and the anatomical characteristics of these injuries in order to facilitate diagnosis of the most critical patients. Methods: To carry out this study, we conducted a retrospective analytical study with epidemiological data on victims of penetrating cardiac injuries. We included two types of patients, with those who underwent autopsy in our institution after death from sharp injury to the heart or great vessels and those who survived with treatment in the emergency department or intensive care unit between January 2015 and February 2022. Results: We included 30 autopsied patients and 12 survivors aged between 18 and 73 years. Higher mortality was associated with prehospital or in-hospital cardiorespiratory arrest (OR = 4, CI [1.71–9.35]), preoperative mechanical ventilation (OR = 10, CI [1.53–65.41]), preoperative catecholamines (OR = 7, CI [1.12–6.29]), preoperative and perioperative adrenaline (OR = 13, CI [1.98–85.46] and [1.98–85.46]), penetrating cardiac injury (OR = 14, CI [2.10–93.22]), multiple cardiac injuries (OR = 1.5, CI [1.05–2.22]) and an Organ Injury Scaling of the American Association for the Surgery of Trauma (AAST-OIS) score of 5 (OR = 2.9, CI [1.04–8.54]; p = 0.0329) with an AUC-ROC curve value of 0.708 (CI [0.543–0.841]). Conclusions: This study identified risk mortality factors in penetrating cardiac injury patients. These findings can help improve the diagnosis and management of these patients. The AAST-OIS score may be a good tool to diagnose critical patients. Full article

In recent years, a series of recommendations have been issued regarding the administration of drugs because of awareness of the serious side effects associated with certain classes of drugs, especially in vulnerable patients. Taking into account the obligation of the continuous improvement of professionals in the medical fields and the fact that we are in the midst of a “malpractice accusations pandemic”, through this work, we propose to carry out a “radiography” of the scientific literature regarding adverse effects that may occur as a result of the interaction of drugs with the physiopathological particularities of patients. The literature reports various cases regarding different classes of drugs administration associated with adverse effects in the elderly people, such as fluoroquinolones, which can cause torsade de pointes or tendinopathy, or diuretics, which can cause hypokalemia followed by torsade de pointes and cardiorespiratory arrest. Also, children are more prone to the development of adverse reactions due to their physiological particularities, while for pregnant women, some drugs can interfere with the normal development of the fetus, and for psychiatric patients, the use of neuroleptics can cause agranulocytosis. Considering the physiopathological particularities of each patient, the drug doses must be adjusted or even completely removed from the treatment scheme, thus requiring the mandatory active participation both of clinician pharmacists and specialists in the activity of medical-pharmaceutical analysis laboratories within the structure of hospitals.

(1) Background: A rare and unexpected consequence of childbirth, labor, or the immediate postpartum period is amniotic fluid embolism (AFE). This study aims to identify AFE cases during or immediately after birth from anesthetic management perspectives. Secondary goals include assessing patient clinical features, obstetric care techniques, birth outcomes, and case survival. (2) Methods: A retrospective observational study assessed AFE patients hospitalized in three Romanian clinical institutions from October 2007 to April 2023. Based on the Society of Maternal-Fetal Medicine (SMFM) criteria, we diagnosed 11 AFE patients. (3) Results: AFE occurred in eight cases (73%) during peripartum, two (18%) within 30 min after placental delivery, and 1 (9%) during a scheduled cesarean surgery. Only one of six cardiorespiratory arrest patients responded to external cardiac massage, while the other five (83%) needed defibrillation. The patients received, on average, five units of red blood cells, six of fresh frozen plasma, and two of activated platelets. Six patients (55%) received factor VIIa infusions. Maternal mortality was 36.3%. Six neonates (75%) needed neonatal resuscitation, and two (25%) died on the second and third days. (4) Conclusions: AFE management necessitates a multidisciplinary approach and the incorporation of advanced life support techniques to optimize outcomes for both the mother and newborn. Full article

ECMO has become a therapeutic modality for in- and out-of-hospital scenarios and is also suitable as a bridging therapy until further decisions and interventions can be made. Case report: A 27-year-old male patient with mechanical aortic valve prothesis had a sudden cardiac arrest (SCA). ROSC had been achieved after more than 60 min of CPR and eight DC shocks due to ventricular fibrillation (VF). The National Ambulance Service unit transported the patient to our clinic for further treatment. Due to the trauma and therapeutic INR, a CT scan was performed and ruled out bleeding. Echocardiography described severely decreased left ventricular function. Coronary angiography was negative. Due to the therapeutic refractory circulatory and respiratory failure against intensive care, VA-ECMO implantation was indicated. After four days of ECMO treatment, the patient’s circulation was stabilized without neurological deficit, and the functions of the end organs were normalized. Cardiac MRI showed no exact etiology behind SCA. ICD was implanted due to VF and SCA. The patient was discharged after 19 days of hospitalization. Conclusion: This case report points out that the early application of mechanical circulatory support could be an outcome-determinant therapeutic modality. Post-resuscitation care includes cardiorespiratory stabilization, treatment of reversible causes of malignant arrhythmia, and secondary prevention. Full article

Several new psychoactive substances (NPS) are responsible for intoxication involving the cardiovascular and respiratory systems. Among NPS, synthetic cannabinoids (SCs) provoked side effects in humans characterized by tachycardia, arrhythmias, hypertension, breathing difficulty, apnoea, myocardial infarction, and cardiac arrest. Therefore, the present study investigated the cardio-respiratory (MouseOx Plus; EMKA electrocardiogram (ECG) and plethysmography TUNNEL systems) and vascular (BP-2000 systems) effects induced by 1-naphthalenyl (1-pentyl-1H-indol-3-yl)-methanone (JWH-018; 0.3–3–6 mg/kg) and Δ⁹-tetrahydrocannabinol (Δ⁹-THC; 0.3–3–6 mg/kg), administered in awake CD-1 male mice. The results showed that higher doses of JWH-018 (3–6 mg/kg) induced deep and long-lasting bradycardia, alternated with bradyarrhythmia, spaced out by sudden episodes of tachyarrhythmias (6 mg/kg), and characterized by ECG electrical parameters changes, sustained bradypnea, and systolic and transient diastolic hypertension. Otherwise, Δ⁹-THC provoked delayed bradycardia (minor intensity tachyarrhythmias episodes) and bradypnea, also causing a transient and mild hypertensive effect at the tested dose range. These effects were prevented by both treatment with selective CB₁ (AM 251, 6 mg/kg) and CB₂ (AM 630, 6 mg/kg) receptor antagonists and with the mixture of the antagonists AM 251 and AM 630, even if in a different manner. Cardio-respiratory and vascular symptoms could be induced by peripheral and central CB₁ and CB₂ receptors stimulation, which could lead to both sympathetic and parasympathetic systems activation. These findings may represent a starting point for necessary future studies aimed at exploring the proper antidotal therapy to be used in SCs-intoxicated patient management. Full article

We report the case of a 34-year-old male patient, a bodybuilding trainer and user of anabolic androgenic steroids (AASs) for 16 years. He was found in cardio-respiratory arrest in his home. By performing a medico-legal autopsy, a severe form of COVID-19, aortic atherosclerotic plaques, and an old myocardial infarction was found. The SARS-CoV-2 RT-PCR test on necroptic lung fragments was positive, with a B.1.258 genetic line. The histopathological examinations showed microthrombi with endothelitis in the cerebral tissue, massive pulmonary edema, diffuse alveolar damage grade 1, pulmonary thromboembolism, hepatic peliosis, and severe nesidioblastosis. The immunohistochemical examinations showed SARS-CoV-2 positive in the myocardium, lung, kidneys, and pancreas. ACE-2 receptor was positive in the same organs, but also in the spleen and liver. HLA alleles A*03, A*25, B*18, B*35, C*04, C*12, DRB1*04, DRB1*15, DQB1*03, DQB1*06 were also identified. In conclusion, death was due to a genetic predisposition, a long-term abuse of AASs that favored the development of a pluriorganic pathological tissue terrain, and recent consumption of AASs, which influenced the immune system at the time of infection.
